1. Product Description
1.1 Introduction
Apacer’s SAFD18S4-M is a solid-state disk (SSD) drive that contains a controller, embedded firmware, and
flash media along with a male connector. Using NAND flash memory devices, the SAFD drive interfaces with
the host allowing data to be seamlessly transferred between the host and the flash devices.
SAFD18S4-M drive is designed with a single-chip controller, offering capacities of up to 128 gigabytes and
providing full support for the SATAⅡ high-speed interface standard. It can operate at sustained access rates
of up to 100 megabytes per second, which is much faster than any other solid-state or traditional SATA drive
currently available on the market. Though built with MLC, this SSD can work in highly demanding
environment as it can withstand ambient temperature from -40°C to +85°C (for certain capacities only).
In addition to buffer management through dynamical allocation, SAFD18S4-M adopts the Apacer-specific
global wear-leveling scheme to allow uniform use of all storage blocks, ensuring that the lifetime of a flash
media can be significantly increased and the disk performance is optimized as well. SAFD18S4-M provides the
S.M.A.R.T. feature that follows the SATA Rev. 2.6, ATA/ATAPI-7 specifications and uses the standard SMART
command B0h to read data from the drive. This feature protects the user from unscheduled downtime by
monitoring and storing critical drive performance.

Functional Block Diagram
SAFD18S4-M drive includes a single-chip SATAⅡ Controller and the flash media, as well as the SATA
standard interface. The controller integrates the flash management unit with the controller itself to support
multi-channel, multi-bank flash arrays. Figure 1-1 shows the functional block diagram.
